hi, i would like to convert a cell vector which is:
1509
1803
'V20E'
1706
1706
'V21N'
1507
1927
to a char vector. then i need to "read" only the second and third character, for example from 1509 to 50.

If there's little control over what's in the cell array, here's one way. This can probably be simplified.
C = {1509; 1803; 'V20E'; 1706; 1706; 'V21N'; 1507; 1927};
charout = repmat(' ',[numel(C) 2]); % preallocate
for k = 1:numel(C)
if isnumeric(C{k}) && isscalar(C{k})
cc = num2str(C{k});
elseif ischar(C{k}) && isvector(C{k})
cc = C{k};
else
error('C(%d) is neither a scalar number nor a char vector',k)
end
charout(k,:) = cc(2:3);
end
charout
charout = 8×2 char array
'50' '80' '20' '70' '70' '21' '50' '92'
If the output needs to be a vector, just use reshape().
charout = reshape(charout.',[],1).'
charout = '5080207070215092'
